Abstract: The present invention is a pre-assembled fitting or coupling having a body, a sleeve, and a nut. One end of the nut has a through bore that is tapered and decreases in diameter toward the end of the nut. The outer surface of the sleeve is tapered as well which facilitates the radial movement of the sleeve segments upon tightening locking the sleeve segments into the proper position on the corrugated tubing. The body contains an inner seal surface with improved geometry that effectively concentrates the sealing load over a pre-determined surface and prevents overloading of the seal surface area. The sleeve of the present invention is divided into four separate segments. The inner surface of the sleeve contains an annular spring. The spring on the inner surface facilitates the removal of the corrugated tube from the nut and coupling body by forcing the segments outward upon loosening the nut.
